The displacement is the vector quantity that defines the distance and direction between two positions. It is a change in your position.
A displacement is a vector in geometry and mechanics that has a length equal to the shortest distance between a point P's initial and final positions.
It calculates the length and angle of the net motion, or total motion, in a straight line from the starting point to the destination of the point trajectory. The translation that links the starting point and the ending point can be used to spot a displacement.
The average velocity, which is a vector for motion over a certain amount of time, is determined by dividing the displacement by the duration of the time interval.
Hence, the displacement is the vector quantity that defines the distance and direction between two positions. It is a change in your position.

I believe you're talking about displacement. It's a directional vector that depicts the movement of a point between two instances.
Answer:
Well since this question was asked years ago, I do believe that there is more solar energy at the equater and less at the poles.
Explanation:
The density of each half of the aluminum block remains the same as the original block, 2.7 g/cm³. Density is an intrinsic property of a material and does not change when the amount of the material changes.
The density of a material remains constant regardless of the amount of that material. The density is an intrinsic property defined as mass divided by volume. When you cut a block of aluminum in half, you are halving both the mass and the volume. Since both are reduced by the same proportion, the ratio of mass to volume (i.e., the density) stays the same. Thus, the density of each half of the aluminum block remains 2.7 g/cm³.

I remember finding the isotope number, Nitrogen-20 by adding the Protons and Neutrons, then I get a new atomic mass. But on here Pottasium-15 is confusing! What neutrons do I add from 19 protons to get 15? Sometimes the teacher throws in impossible problems.
super super late ans but im up late n looking 4 interesting Qs...
Potassium-15 is confusing indeed! What neutrons can one add to a nucleus with 19 protons to get a mass of 15? anti-matter cannot do it as scientists have generally agreed that anti-matter has the same mass as regular matter but with an opposite spin.
the ans actually doesnt exist when the Q was originally asked but in 2017, Washington State University physicists created a fluid with negative mass. so theoretically a "negative neutron" will have a mass of -1. combining 4 of such exotic particles to 19 protons will create K-15; assuming there is no explosion from the combination.
